14 IPwatchD is a simple daemon that analyses all incoming ARP packets in
15 order to detect IP conflicts.
16
17 Default configuration file uses "automatic configuration mode" with
18 "passive protection mode" and it should be the best option for most
19 systems.
20
21 Configuration mode applies to the daemon instance and it specifies how
22 the list of network interfaces that should be monitored will be
23 obtained. In automatic configuration mode IPwatchD detects all network
24 interfaces automatically and sets passive protection mode for them. In
25 manual configuration mode it is up to the system administrator to spec‐
26 ify list of interfaces and protection modes in configuration file.
27
28 Protection mode specifies the action that will be performed when IP
29 conflict is detected. In active protection mode IPwatchD protects your
30 host before IP takeover by answering gratuitous ARP requests received
31 from conflicting system. In passive protection mode it just records
32 information about IP conflict through standard syslog interface.
33
34 IPwatchD also supports execution of user defined scripts. See
35 ipwatchd.conf(5) and ipwatchd-script(1) for more details.
36
38 The following options are supported:
39
40 -c --config
41 Specifies path to configuration file.
42
43 -d --debug
44 Enables debug mode. Debug information are recorded through sys‐
45 log with "daemon" facility and "debug" priority.
46
47 -t --test
48 Enables testing mode that is useful only for debugging. In this
49 mode every received ARP packet is considered to be conflicting.
50
51 -v --version
52 Prints program version to standard output.
53
54 -h --help
55 Prints short help information to standard output.
56
58 See ipwatchd.conf(5) for more details.
